When I removed my emblems I used alcohol to clean the last bit of residue and get rid of the Goof Off before applying the new emblems and the alcohol dulled my clear coat. I had to use a polish to get the shine back where I rubbed the alcohol in. It is great for getting rid of contaminants but use it sparingly and don't rub it in really hard..
